Comme= nt # 54 on bug 10617= 5 from tempel.j= ulian@gmail.com 
You should btw. also set CPU clock governor to either acpi-cpu=
freq performance
or intel_pstate performance, since governors like powersave, ondemand or
schedutil can already cause severe stuttering at vsynctester.com, even with=
out
a compositor.

The result should be 100% stutter free, at least that's the case for me with
amdgpu.dc=3D0. This way you should be able to be absolutely sure if the res=
ult is
badly affected by amdgpu.dc=3D1.
